Coronary Artery Disease - Correlates Between Diastolic Auditory Characteristics and Coronary Artery Stenoses

A noninvasive approach to detecting coronary artery disease analyzes thoracic sounds to isolate acoustical correlates of stenosed coronary arteries. The analysis includes time windowing, frequency (power spectra) windowing, and averaging of thoracic sounds from normal and diseased patients. Initial results indicate that an above normal percentage of high-frequency (180-300 Hz) energy is closely associated with narrowed coronary arteries.
